Rarely my phone will power off when I plug it in (read two maybe three Times since March), one in v6 rooted and one on broken out 1.2 or 1.3. If there was another I do not recall what I was running. It happens occasionally when not plugged in also, maybe 5-7 times. I think it is just a random reboot that fails to power back on
